An

**arithmetic sequence**is a list of numbers where each number is equal to the previous number, plus a constant. The constant is called the common difference, often denoted as*d*.To find the sum of a given arithmetic sequence as well as the n

^{th}term in the sequence, simply fill in the necessary values below and then click the “Calculate” button.**a _{10}** (the value of the 10

^{th}term) = 32

**s _{10}** (the sum of the first 10 terms) = 185

**Formulas used:**

**a _{n}** (the value of the n

^{th}term) = a

_{1}+ ((n−1)*d)

**s _{n}** (the sum of the first n terms) = (n/2) * (2a

_{1}+ (n−1)*d)
